Subject: [PATCH v2 0/2] i2c: core: Introduce i2c_client_get_device_id helper

Introduces a new i2c helper to query driver match tables and recover the
identity of the bound device. This helper should help with the migration
of existing drivers to use the new i2c_driver .probe_new callback, which
does not provide the device id with the pointer to the driver data as the
previous .probe callback.

As part of the patchset, migrated the bmp280 IIO driver to .new_probe
callback using the new helper.

Changes from v1 --> v2:
* Add further clarification that the device queried needs to be bound to
  the driver.
* Drops extra newline after function return.
* Discard unrelated style changes.
